Abstract

The present invention relates to an interlinked composite fire extinguishing bomb which is an explosive device mainly used for extinguishing forest conflagration and prairie conflagration. The present invention is provided with a mother bomb, an initiator and a safety device, wherein the circumference of the mother bomb is provided with multiple groups of sub bombs. Ignition conducting wires extracted from electric shock detonators in sub bomb center satchel charges at the center of the bombs are connected with the initiator and are controlled by the safety device and ignition push rods. Each group of sub bombs comprises one big and one small sub bombs which are loaded into a tapered barrel; each ignition push rod is inserted between sub bombs in each group; the end head of the ignition push rod is conductive metal, and the rear end is a cambered surface; all of the cambered surfaces form into an upper cambered surface. When the present invention is used, two bombs are as a group and are loaded into a bomb release device by a helicopter, and the fire extinguishing media of the two bombs are respectively sand stone and carbon dioxide dry powder. When the bombs are released, firstly the sand stone fire extinguishing bomb is released, and then, the carbon dioxide dry powder fire extinguishing bomb is released. When the fire extinguishing bombs are released, interlinked impact explosion can be arisen if any ignition push rod on the spherical surface contacts trees or hard objects; the sand stone fire extinguishing bomb extinguishes conflagration and the carbon dioxide dry powder fire extinguishing bomb partitions the contact between powder and air to thoroughly extinguish the conflagration.

Description

A chain of primary and secondary fire extinguisher bomb

One, technical field

The present invention is a kind of device that puts out a forest fire with the grassland big fire that is mainly used in.

Two, background technology

Since ancient times, forest fire and grassland big fire have caused immeasurable loss for human resource and environment, people have taked various original and modern fire extinguishing means, but big fire is difficult to control to certain intensity of a fire, as spray, aircraft is thrown and is spread dry powder water etc., a large amount of manpowers of the needs that have, what have costs dearly, and effect is not ideal.

Three, summary of the invention

The present invention utilizes shock wave that serial blast produces and fire extinguishing sandstone, the fire-suppressant gas that thereupon scatters, and reaches the thoroughly purpose of fire extinguishing of large tracts of land.

Female bullet that this fire extinguisher bomb includes a center has the multicomponent bullet on every side, also has trigger and safeties, be inserted with the ignition push rod between each component bullet, female bullet has the blasting charge with the center of each minute bullet, pack for firing-fighting medium and with shell case on every side, mother's bullet is connected with trigger with the ignition lead that the interior electric shock of each minute bullet center blasting charge detonator is drawn and controlled by safeties and ignition push rod, and the ignition lead is connected in series between the bullet of every component bullet.Every component bullet is interior each the one piece of branch bullet of size of conically shaped of packing into.The ignition push rod front end that inserts between each component bullet is a conducting metal, and the rear end is an arcwall face, and each arcwall face is formed spherical.A chain of primary and secondary fire extinguisher bomb is two pieces of supporting uses, one piece with firing-fighting medium be sandstone, another piece with firing-fighting medium be carbon dioxide dry powder, for the eruption fire extinguishing that increases carbon dioxide dry powder fire extinguisher bomb is renderd a service, when female bullet of encapsulation and branch bullet, be added to 1.5-2 atmospheric pressure in the body, the branch bullet number around female bullet is 10-50 piece.

When in case forest fire or prairie fire take place, can use helicopter to throw, two bullets that at first array are equipped with different firing-fighting mediums are contained on the vertical paracrate of aircraft, the safeties of each bullet promote downwards, drop a bomb one by one in the overhead mobility of big fire, the fire extinguisher bomb of dress sandstone firing-fighting medium at first falls, the fire extinguisher bomb of another dress carbon dioxide dry powder medium follows the whereabouts closely, when any one ignition push rod of sphere of fire extinguisher bomb touches trees or hard thing, can inwardly promote to ignite push rod, the ignition lead of conducting trigger and female bullet center blasting charge causes female bullet blast, while is the ignition lead of each component bullet of conducting also, in the blast of female bullet in a flash, each minute bullet will disintegrate and take off to the four sides, pass the blast of discontinuity between jungle, every bullet shock wave drive sandstone spray on four sides and hit, extinguish the blaze, reburn, the fire extinguisher bomb blast of second piece of band carbon dioxide dry powder medium for avoiding remaining flare, can effectively cut off contacting of flare and air, fire is thoroughly extinguished.More than the tens of kilograms of each fire extinguisher bomb, its fire-fighting area is big and effective.

Four, description of drawings

Accompanying drawing 1 is the interior section structural representation

Accompanying drawing 2 is for igniting the cabling schematic diagram

Five, the specific embodiment

Example 1, be that the fire extinguisher bomb of sandstone is an example to make firing-fighting medium, the center of fire extinguisher bomb is bigger female bullet 1, female bullet 1 center is blasting charge 1-1, the electric shock of interruption detonator 1-2 is arranged in it, peripheral extinguishing chemical 1-3 is sandstone, outermost is metal cast iron shell case 1-4, and the ignition lead 8 that interruption electric shock detonator 1-2 draws is connected with trigger 4, is communicated with controlled by safeties 7 and ignition push rod 6.Be with tens of component bullets 2 outside female bullet 1, (as establishing about 30 groups) is covered with around female bullet 1, divide the structure of bullet 2 identical with female bullet 1 structure, just volume is less, peripheral branch bullet 2 per two pieces be one group, size is slightly different, be contained in up and down in the conically shaped 3, divide outstanding traverse point of bullet 2 bodies and conically shaped 3 inwalls to hold outward to collude 3-1 and contact, the ignition lead 8 of every group of two pieces of branch bullets 2 is serial connection modes, two ends are connected with trigger 4 and are subjected to safeties 7 and ignite push rod 6 controls, have only to promote them forward and just connect ignition, ignite lead 8 cloth at female bullet 1 shell case 1-4 outer surface.The ignition lead 5 that is mounted with a trigger 4 and draws 2 on minute bullet.At the ignition push rod 6 that 2 on each component bullet is inserted with, can make of engineering plastics, just the termination 6-1 that inserts is a conducting metal, and the rear end is lonely shape face 6-2, and all lonely shape face 6-2 form a sphere.Safeties 7 are push rod shapes that a front end has two metal contacts, and push rod and arcwall face are made of engineering plastics.

Example 2: extinguishing chemical is the fire extinguisher bomb of carbon dioxide dry powder, and its structure is the same with the sandstone fire extinguisher bomb, is in female bullet and the interior extinguishing chemical 1-3 employing carbon dioxide dry powder of each minute bullet, inwardly is pressurized to 1.5-2 atmospheric pressure during its encapsulation and encapsulates.
